Physiological and biochemical characteristics of genetically modified winter wheat

Aim. Analysis of physiological and biochemical characteristics genetically modified wheat with partially suppressed activity the proline dehydrogenase gene. Methods. Determination (PDH) activity, free L-proline (Pro); carbohydrate content (sucrose fructose). Results. It was established that under conditions water deficit in plants integrated elements forming double-stranded RNA suppressor pdh gene, there is a partial inhibition enzyme an increase proline. Changes metabolism stress first hours after rehydration were noted, while sucrose / fructose ratio control significantly decreases during dehydration normalizes when supply restored, this indicator almost does not change short-term stress. Conclusions. Partial suppression gene leads to content, fluctuations which contribute maintenance balance.
